When the -p option is given to clang-tidy, it doesn't need the compile
command line to be appended. It can get everything it needs from the
compile_commands.json file in the directory specified with the -p option.
When the compiler being used is not the system default compiler,
clang-tidy has been observed to pick up the wrong headers when the
compiler command line is given, but not if only the -p option is used.
Therefore, don't append the compiler command line if -p is present in
the <LANG>_CLANG_TIDY target property.

Define the entry point to each mode as an option for the `cmake`
program, but reference the options for that mode as part of stand-in
`cmake-<mode>` programs.
Update the --debug-trycompile documentation to account for recent
changes to try_compile. Mention where in the build tree to find
artifacts when using said option.
Change the SOURCE_FROM_ARG keyword to try_compile to SOURCE_FROM_CONTENT
(which we can do because it was recently added and hasn't been in a
release yet). The new name should be clearer as to what it does, and
also more consistent with the CONTENT arguments to some other commands.
Also, fix a typo in an error message.
Add ability to copy try_compile (and try_run) source files from
arbitrary locations into the operation directory. This is included for
the sake of completion and consolidation, although use cases which
actually require this may be rare.
Add ability to "feed" try_compile (and try_run) sources more directly,
either from literal content, or from a CMake variable which contains
literal content. This saves the user from needing a separate step to
write the content to a file, and allows for the sources to only exist in
the scratch directory.
Link policy explaining BYPRODUCTS.
Apply the change from commit 00b788e85e (Help:custom_command: link
policy on BYPRODUCTS, 2022-09-09) to `add_custom_target` docs too.

Introduce a new signature for the project flavor of try_compile (and
try_run) which removes the `bindir` argument and adds a required PROJECT
tag. This is similar to the SOURCES flavor added by commit aa9220d3
(try_compile: Add keyword-dispatched signature, 2022-09-02).

Replace our hard-coded default for `/Zi` with a first-class abstraction
to select the debug information format an enumeration of logical
names. We've long hesitated to do this because the idea of "debug
information format" touches on related concepts on several platforms.
Avoid that scope creep by simply defining an abstraction that applies
only when targeting the MSVC ABI on Windows.
Removing the old default flag requires a policy because existing
projects may rely on string processing to edit them and choose a
runtime library under the old behavior. Add policy CMP0141 to
provide compatibility.
